I'm thinking about putting the Vetus tank in and then putting the original tank under a new console as I will have a 60 mile round trip to fill up with fuel.

The guy i talked to in Dartmouth who teaches the matlo's to drive Pac's, said they work on a range of 90 miles on a standard tank, flat out, i don't think mine would do that, think i would get about 70 ish miles.

Agreed, the previous owner of Old Spice just made Alderney from Lymington, about 70 miles. The weight of an extra 100 litres isn't going to effect the outstanding performance

I used Merc/Mariner grey flexible fuel line and drilled an additional 3 holes in the engine bay to fuel tank area to take the lines to the fuel pump.

Ideally use ISO 7840 hose which would then pass a survey for commerical work in the future if you ever decided to go down this route and again would save having to replace it. I got away with the Merc stuff because a clause in the Yellow code says fuel lines should be ISO 7840 or changed to this standard when next replaced.

Why? I can understand vibration and work-hardening being an issue and rupture strengths, etc, but why is salt water an issue with copper pipe? I thought it was perfectly suitable for use in sea water including in immersion. Have I missed something?

Jono, I was thinking about corrosion of a pipe hidden under deck which can't be seen, but you raised an equally valid point on vibration. Fitting any fixed pipe would also be a nightmare unless the engine is out.

I'm not 100% sure but I think any boat that has to have a BSS as mine will has to have rigid fireproof piping except for a flexible connection to the engine. I've never heard of anyone having problems with copper, either for steering hydraulics or fuel.

Copper on its own will corrode happily in salt water going a lovely shade of blue, I suspect that a lot of people are using Copper nickel without realising it . Copper nickel offers better resistance to corrosion and is commonly used for things like brake pipes etc Des
